JlB-HANK.

SPECIFICATION formingpart of Letters Patent No. 423,859, dated March 18, 1890.

Application filed October 11, 1889- Serial No. 326,670. (No model.)

To all whom it may concern:

Be it known that I, DAVID OROWELL, of Yarmouth, in the county of Barnstable, State of Massachusetts, have invented a certain new and useful Improvement in J ib-Hanks, of which the followingis a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is an elevation of my improved j ibhank; Fig. 2, an edge elevation of the same, and Fig. 3 a side elevation representing the hank as opened.

Like letters of reference indicate corresponding parts in the different figures of the drawings.

My invention relates to a detachable hank for securing a jib or other sail to the stays; and it consists in certain novel features, hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper, and more effective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all con versant with such matters from the following explanation.

In the drawings, A represents the bank considered as a whole. The hank is constructed of metal and is formed in two sections 1) d. These sections are of the same general shape, and when closed form two loops or eyes f g for the stays and leaches. The sections overlap at their lower ends and are pivoted together at h. Their upper ends also overlap at 'i to prevent lateral movement and too great a strain on the pivot. The central portion j of the section Z) is elongated inwardly and has a hook 7c formed thereon. The corresponding portion of the section (1 is grooved atl to receive the portion j, and a hook m is formed therein, adapted to take on said hook 7.: when the sections are closed and lock them firmly together. A pin 19 projects laterally from the hook 7a and a similar pin g from the companion m. The parts are so constructed that when the sections are brought together considerable force is necessary to spring the hook on over the hook 7c, the elasticity of the metal permitting this, and yet offering sufficient resistance to the pressure of the ropes to prevent -them accidentally separating. When it is desired to separate the sections to remove the ropes, a marline-spike or similar article is inserted between the pins 19 q and employed as a lever to lift or spring the hook on upward sufficiently to release it from the hook is, in a manner which will be readily understood by all conversant with such matters without a more explicit description.

It will readily be seen that by the use of my improvement the sails can be much more quickly bent or unbent than when hanks of the ordinary construction are employed.

My invention may also be employed to take the place of a link in a chain when broken, or as hooks for the gaif-topsail sheets, masthooks, &c. As the greater portion of the strain from the ropes is borne by the ends of -the loops f g where the sections overlap, as

described,-the sections are little liable to become unhooked. Moreover, the parts being constructed of spring metal, it becomes necessary to exert a great strain on the hooks.

and at a point adjacent thereto, as the pins 19 q, before they can readily be separated.

Having thus explained myinvention, what I claim is The hank A, constructed in sections 1) d, piv-' and pin 19, and the section (1 provided with the groove Z and companion hook on and pin q, substantially as described.
